Fig. 3From: Microtubule cytoskeleton-disrupting activity of MWCNTs: applications in cancer treatmentTubulin association with MWCNTs into biosynthetic filaments. Tubulin heterodimer structure. In the dimer, α-tubulin is colored in dark red and β-tubulin in pink. Head-to-tail tubulin heterodimer alignment assembles protofilaments of 4 nm diameter that intermingle with the MWCNTs and from biosynthetic tubulin filamentsBack to article page
